Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 29+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

So I'm a bit confused about the injector replacement, were they replaced before or after the engine long block replacement??

So, I'm thinking one of those replacement injectors failed and caused damage to the original engine, Since they were swapped to the new engine, I am suspecting that this is your cause. About the ONLY cause that can result in raw fuel draining out of the exhaust system is an injecto(s) that is stuck open. This WILL cause a NO start also. It is VERY HIGHLY recommended to replace ALL those injectors again BEFORE attempting to get the engine running. IF you happen to get it running with these injectors, charnces are VERY HIGH that you will burn up another engine due to faulty injector(s)...
